Two schedules in every manual
Most owners follow one schedule and do not know a second one exists. Manufacturers publish a normal schedule and a severe service schedule, and the second is shorter on nearly every item.
What puts a vehicle on it is not dramatic. Short trips, extended idling, dust and unpaved roads, towing, carrying weight, and sustained low temperatures. A vehicle here that commutes a few miles in winter and tows in summer qualifies twice over.
Following the normal schedule on a vehicle living a severe one is the most common maintenance mistake there is, and it is invisible until something fails early.
Two seasons, two different lists
Maintenance in Montana is not evenly distributed through the year, and planning it around the seasons gets more out of the same money.
Before winter: coolant protection tested rather than assumed, battery and charging checked, tires and tread depth looked at, wipers and washer fluid, and the heater, which runs off the cooling system.
Before summer: air conditioning while there is time to fix it, cooling system again if you tow, brakes if the vehicle pulls weight, and alignment after a winter of frost heave.
The point of a schedule is the things you do not notice
Brake fluid absorbs moisture. Coolant loses corrosion protection. Belts and hoses age whether the vehicle is driven or not. Suspension components wear gradually enough that a driver adapts to the result.
None of that announces itself. The schedule exists because the failure mode of each item is silent until it is not, and the replacement cost at the right time is a fraction of the cost at the wrong one.
One store, sixteen services
What makes this practical is not having to drive the vehicle to three places. Billings runs sixteen services, so tires, oil changes, suspension, engine work and the rest happen at one address, with one history on the vehicle.
For a business running several light vehicles, the version of this that works is a fleet account with the schedule attached.
